TRASH BURNER COVER Filed Dec. 6, 1963 United States Patent 3,264,806 TRASH BURNER COVER Gerald P. Trombley, New Hyde Park, N.Y. (9 N. Maryland Ave., Port Washington, N.Y.) Filed Dec. 6, 1963, Ser. No. 328,667 7 Claims. (Cl. 220-24) This invention relates to domes-tic trash burners, and more particularly to a novel sa fety cover for containers in which trash is burned.

The primary object of the invention is the provision of a more efficient and practical device of the kind indicated, which is upwardly domed to enable the safe burning of trash in an otherwise over-filled container.

Another object of the invention is the provision of a rugged and long-lasting device of the character indicated above which is adapted to be constructed of heavy wire or light bar stock.

A further object of the invention is the provision of a device of the character indicated above, which embodies novel and more reliable means for retaining the device securely and removably in place on the top of a container, such as a metal trash barrel or can.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.

. In the drawings:

FIGURE 1 is a fragmentary side elevation, partly in phantom lines, showing a device of the present invention in place on a trash barrel.

FIGURE 2 is a top plan view of FIGURE 1;

FIGURE 3 is a vertical transverse section taken on the line 33 of FIGURE 2;

FIGURE 4 is an enlarged fragmentary view like FIG- URE 3; and

FIGURE 5 is a top plan view, on a reduced scale, like FIGURE 2, showing another form of the invention.

Referring in detail to the drawings, an open-top metal trash container, such as a barrel B, is shown as having a side wall 10, around the upper edge of which an external bead 12 is provided, and with which portions of a safety cover 14 is engaged, in accordance with the present invention.

The cover 14 comprises a plurality of relatively close and uniformly spaced concentric rings which comprise an outer ring 16 of maximum diameter, an inner ring 18 of minimum diameter, and intermediate rings 20. The intermediate rings 20 are positioned at progressively higher levels, from the outer ring 16 to the inner ring 18, which is similarly spaced above the innermost of the intermediate rings.

The rings are supported and fixed in this relationship by means of diametrically opposed, inwardly and upwardly angled rods 22, which are equally spaced around the device. The rods 22 are right-ang-ularly related components of two segmental rod sections 24, which comprise the rods 22 which are joined, as indicated at 26, at their convergent ends. The rods 22 terminate, at their outer ends, in short perpendicular pendant vertical portions 28, which are angled upwardly toward each other, in each section 24, and which have inwardly extending horizontal support portions 30, on their lower ends. The horizontal portions terminate, at their inner ends, in pendant vertical portions 32, which merge, at their lower ends, into the related ends of horizontal arouate retaining bars 34. The arcuate bars 34 have the same centers of curva ture as the rings 16, 18, and 20, and are located midway between the outer ring 16 and the adjacent one of the intermediate rings v20.

3,204,866 Patented Sept. 7, 1965 As shown in FIGURES 3 and 4, the rings 16, 18, and 20 are suitably secured and fixed upon the tops of the diametrical rods 22, and the junctions 26 are joined together, as by means of welding 36.

In use and operation, the cover 14 is secured removably in place on the top of the barrel B, by inserting the arcuate retaining bars 34 into the barrel so that the horizontal portions 30 rest upon the top of the barrel, and preferably upon the bead 12. The components'of the device can be so proportioned and made resilient, so that insertion of the retaining bars 34 into the barrel involves some inward flexing of the bars 34, so that they assume strong spring biased frictional retentive engagements .with the inner surfaces of the barrel sidewall 10, which elimin'ates accidental removal of the covering during transportation and handling of the barrel B, and the effects of wind thereon.

In the form of the invention shown in FIGURE 5, the rings 20a are formed from a single continuous bar or rod which is spiralled from the center and is thereat secured, as indicated at 21a to the bars 22a where they are joined, and terminates at 23a, where it is suitably secured to the outer convolution of the coil.

Although there have been shown and described preferred forms of the invention, it is to be understood that the invention is not necessarily confined thereto, and that any change or changes in the structure of and in the relative arrangements of components thereof are contemplated as being within the scope of the invention as defined by the claims appended hereto.

What is claimed is:

A trash burner comprising an open-top container having a sidewall and a perforated cover removably engaged on the top of the container, said cover having retaining means extending downwardly therefrom and securabl'y engaged with the inner surface of the sidewall of the container, said retaining means being resilient and being spring-pressed in engagement with the inner surface of the container side wall, and comprise horizontal arcuate retaining bars.

2. A safety cover of the character described comprising an outer ring of maximum diameter, an inner ring of minimum diameter, spaced intermediate rings located between and concentrically-spaced from each other and from the outer and inner rings, said inner ring being spaced above the outer ring, the intermediate rings being on progressively higher levels with respect to the outer ring and spaced below the inner ring, and radial rods secured to the rings, said rods having inner end portions extending across the opening of the inner ring, said rods having outer ends and inner ends, the inner ends of the rods being joined together, vertical pendant portions on the outer ends of the rods, said vertical portions terminating at their lower ends in radially inwardly extending horizontal support portions, said support portions terminating at their inner ends in pendant perpendicular portions.

3. A safety cover of the character described comprising an outer ring of maximum diameter, an inner ring of minimum diameter, spaced intermediate rings located between and concentrically-spaced from each other and from the outer and inner rings, said inner ring being spaced above the outer rings, the intermediate rings being on progressively higher levels with respect to the outer ring and spaced below the inner ring, and radial rods secured to the rings, said rods having inner end portions extending across the opening of the inner ring, said rods having outer ends and inner ends, the inner ends of the rods being joined together, vertical pendant portions on the outer ends of the rods, said vertical portions terminating at their lower ends in radially inwardly extending horizontal support portions, said support portions terminating an outer ring of maximum diameter, an inner ring of minimum diameter, spaced intermediate rings located between and concentrically-spaced from each other and from the outer and inner rings, said inner ring being spaced above the outer ring, the intermediate rings being on progressively higher levels with respect to the outer ring and spaced below the inner ring, and radial rods .secured to the rings, said rods having inner end portions extending across the opening of the inner ring, said rods having outer ends and inner ends, the inner ends of the rods being joined together, vertical pendant portions on the outer ends of the rods, said vertical portions terminating at their lower ends in radially inwardly extending horizontal support portions, said support portions terminating at their inner ends in pendant perpendicular portions, the inner ends of the support portions being spaced inwardly from the outer ring, and outwardly bowed retaining bars extending between and fixed to the lower ends of the pendant perpendicular portions of adjacent radial rods, the vertical pendant portions of adjacent radial rods being downwardly divergent relative to each other.
